Hamilton and Leclerc Acknowledge Mercedes' Commanding Edge in Battle for Supremacy
As the Formula 1 circus prepares for the Chinese Grand Prix, Lewis Hamilton and Charles Leclerc have both publicly recognized Mercedes' substantial performance superiority over their Ferrari rivals. The candid admissions from both drivers paint a picture of a clear hierarchy in the current competitive landscape.

Looking ahead to this weekend's Chinese Grand Prix, the conversation surrounding competitive balance has taken center stage, with two of the sport's most prominent drivers providing frank insights into the current state of play.
Lewis Hamilton and Charles Leclerc have not shied away from acknowledging Mercedes' dominant position in the 2026 season. Both drivers have spoken openly about the "huge" advantage the Silver Arrows have established, effectively conceding that Ferrari currently trails their rivals in terms of overall package performance.
The assessment from Hamilton and Leclerc underscores the significant performance gap that has emerged between the two Scuderia outfit and the Mercedes team. Such candid observations from the drivers themselves suggest that the competitive hierarchy is decisively tilted in Mercedes' favor as the season unfolds in China.

Full Regulation Text
Article 4.3
ADUO Operational and Financial Measures and Eligibility Criteria
Chapter: APPENDIX C5: HOMOLOGATION AND DEVELOPMENT OF POWER UNITS, FUEL AND OIL FOR 2026-2030
In Simple Terms
This rule gives struggling power unit manufacturers extra development opportunities to catch up. If a manufacturer's engine is 2-4% slower than the best engine, they get 1 extra upgrade per season for two seasons. If they're 4% or more behind, they get 2 extra upgrades per season instead. These upgrades are one-time grants and don't stack within the same season.
- ADUO (Aid to Disadvantaged Users of Older power units) provides extra homologation upgrades for manufacturers falling behind on performance
- Eligibility is based on ICE Performance Index: 2-4% gap = 1 upgrade per season; 4%+ gap = 2 upgrades per season
- Upgrades are granted for two consecutive seasons (N and N+1) but don't accumulate within a single season
- Manufacturers must also reduce their Cost Cap spending downward when receiving these benefits
Official FIA Text
At the end of each of the ADUO periods specified above, every PU Manufacturer granted ADUO may implement further upgrades to their homologated Power Unit (as described in Article 3.3 of this Appendix), extend the usage of their Power Unit Test Benches for Restricted Testing (as described in Article F5.2.7) and must make a downward adjustment for Cost Cap purposes (pursuant to Article 4.1(t) of the Power Unit Financial Regulations). a. PU Manufacturers whose ICE Performance Index is at least 2% but less than 4% below the best-performing ICE will be eligible for: i 1 additional homologation upgrade in season N ii 1 additional homologation upgrade in season N+1 b. PU Manufacturers whose ICE Performance Index is at least 4% below the best-performing ICE will be eligible for: i 2 additional homologation upgrades in season N ii 2 additional homologation upgrades in season N+1 ADUO homologation upgrades are not cumulative within a season and will only be granted following the first occasion that the PU Manufacturer is assessed by the FIA as eligible for ADUO according to the criteria in this Article. [The proposed 2% threshold and subsequent resolution of the ICE performance index will be validated or adjusted after conclusion of the ongoing activities between PU Manufacturers and F1 Teams related to the on-track ICE performance measurement]
Article 4.4
Application of ADUO homologations
Chapter: APPENDIX C5: HOMOLOGATION AND DEVELOPMENT OF POWER UNITS, FUEL AND OIL FOR 2026-2030
In Simple Terms
Power unit manufacturers can use engine upgrades (called ADUO homologations) that they've been granted in the current season, plus any upgrades they were approved for from the previous season. If they don't use an upgrade by the final race of the season, they lose it. Teams that don't get approved for upgrades in the first two review periods of the season can't try again in the final period.
- Manufacturers receive a limited number of engine upgrade slots per season based on performance-based grants
- Upgrades approved in the previous season carry over and stack with current season allowances
- Unused upgrades must be introduced by the final race or are forfeited permanently
- Missing upgrade approval in the first two periods disqualifies a manufacturer from the third period window
Official FIA Text
a. If a PU Manufacturer receives an ADUO grant for one or two ADUO homologation(s) upgrade(s) in season N, only the corresponding number of one or two ADUO homologation(s) is(are) permitted in that season in addition to any ADUO homologation(s) granted in season N-1 and applicable to season N. b. Any ADUO homologations awarded in season N-1 for use in season N will be in addition to those which may be granted in Season N. c. Any unused ADUO homologation upgrade awarded in season N for use in season N, if not introduced by the final Competition of the season, are forfeited. d. PU Manufacturers not granted ADUO following either of the first two ADUO Periods of season N are not eligible for ADUO in the last period of that season (as described in Article 4.2 of this Appendix). The FIA reserves the right to implement corrective actions, at its sole discretion, should the upgrades implemented under Article 3.3 result in a competitive imbalance. Any such actions will be discussed in good faith with all PU Manufacturers
